Consult Fable

Ask Fable — the frontier tier above Opus — for judgment. This is a consultation, not a delegation: Fable reads and advises, it does not edit. For implementation hand-offs, use claude-exec instead.

When to use

• A design decision with real trade-offs, where you want a frontier-tier verdict.
• A debugging dead end: present the symptoms and your hypotheses, ask what you're missing.
• A close review call (ship or hold, is this finding real, is this API shape right).

Not for lookups, mechanical work, or anything a cheaper model answers just as well — Fable is the most expensive tier (a trivial round trip already costs ~$0.5).
